trinomials

Three-term algebraic expressions

Trinomials are algebraic expressions containing exactly three terms, typically connected by plus or minus signs: x² + 2x + 1 is a trinomial.

The term appears most often in algebra courses, where factoring trinomials is a foundational skill.

In taxonomy, a trinomial is a three-part scientific name that identifies a subspecies.
